进行了一项研究，以评估砷 (As) 污染地区土壤酶（淀粉酶、蔗糖酶、纤维素酶和脲酶）和土壤理化参数的季节性变化。本次实验选择了印度西孟加拉邦普尔巴斯塔利市的十个不同采样点，并将收集到的数据与对照区布尔德万大学农场的数据进行了比较。所有实验土壤样品中的砷浓度都很高。仅脲酶和淀粉酶活性被发现显着变化（p < 0.05），记录了季风后时期土壤酶活性和有机碳含量之间的关系。再次发现，在季风前和季风后时期，脲酶和纤维素酶活性分别随土壤砷含量显着变化（p < 0.05）。两个季节的聚类分析都记录了类似的观察结果。此外，除季风后时期的脲酶外，所有测试的土壤酶活性均与季风前和季风后时期的土壤湿度均显示出显着关系（p < 0.01，p < 0.05）。因此，研究土壤酶活性和理化参数可能有助于评估砷对土壤生化质量的影响。
A study was conducted to assess the seasonal variations of soil enzymes (amylase, invertase, cellulase, and urease), and physicochemical parameters of soil in an arsenic (As)-contaminated area. Ten different sampling sites of Purbasthali, West Bengal, India, were chosen for this experiment, and the collected data were compared with that of the control area, Burdwan University Farm, Burdwan. The As concentrations were found to be high in all experimental soil samples. Only urease and amylase activities were found to vary significantly (p 0.05) relationships were recorded between soil enzyme activities and organic carbon content during the post-monsoon period. Again urease and cellulase activities were found to vary significantly (p < 0.05) with soil As content in both pre- and post-monsoon periods, respectively. Similar observations were recorded from cluster analysis in both the seasons. Moreover, all tested soil enzymes activities except urease in post-monsoon period have shown significant relationship (p < 0.01, p < 0.05) with soil moisture in both pre- and post-monsoon periods. Therefore, it is suggested that the study of enzymatic activities and physicochemical parameters of soil may be helpful in assessing the effects of As on the biochemical quality of soils.
